Abstract

Trattasi di una rosetta, per maniglie di serrature a scrocco, inglobante una molla di richiamo.Tale rosetta risulta costituita, sostanzialmente, da un disco, provvisto di un foro centrale e di una pluralità di fori perimetrali, portante coassialmente, con semplice appoggio, una molla di acciaio, con estremità ripiegate, rispettivamente, verso l'esterno e verso l'interno. Con tale molla, coopera un elemento discoidale di ritegno, in corrispondenza del cui centro è ricavato un foro quadro, di sezione correlata al perno fissato nel mozzo delle maniglie medesime. I suddetti molla ed elemento discoidale sono vincolati, sul disco precitato, mediante una apposita struttura anulare, presentante una porzione centrale rilevata, opportunamente sagomata.It is a rosette, for handles of latch locks, incorporating a return spring. This rosette is substantially constituted by a disk, provided with a central hole and a plurality of perimeter holes, bearing coaxially, with simple support, a steel spring, with ends folded outwards and inwards respectively. A disc-shaped retaining element cooperates with this spring, at the center of which a square hole is obtained, with a section related to the pin fixed in the hub of the handles themselves. The aforementioned spring and disc-shaped element are constrained, on the aforementioned disc, by means of a special annular structure, having a detected central portion, suitably shaped.
